A group of students measure the length and width of a random sample of beans. They are interested ininvestigating the relationship between the length and width. Their summary statistics are displayed in thetable below. All units, if applicable, are millimeters.Mean widthStandard deviation of widthMean heightStandard deviation of heightCorrelation coefficient7.50.90913.3292.040.756Round your answers to three decimal places.The students are interested in using the width of the beans to predict the height. Calculate the slope ofthe regression equation.Write the equation of the line of best fit that can be used to predict bean heights. Use x to representwidth and y to represent height.What fraction of the variability in bean heights can be explained by the linear model of bean height vs.width? Express your answer as a decimal.If, instead, the students are interested in using the height of the beans to predict the width, calculate theslope of this new regression equation.Write the equation of the line of best fit that can be used to predict bean widths. Use x to representheight and y to represent width.
